Question

if the volume of a scuba tank filled with air remains constant and its temperature goes down, what happens to its pressure?

Answer 1

Answer:

Decreases

Explanation:

Ideal gas law:

PV = nRT

where P is absolute pressure,

V is volume,

n is number of moles,

R is gas constant,

and T is absolute temperature.

If V is constant and T decreases, then P must decrease.
